虽然人们早就知道空间间接激子的基态是光学非活性的，但它与玻色-爱因斯坦凝聚（BEC）的相关性一直被忽视。过去，激子BEC的特征以激子发出的定向发光或相干性的形式被寻求。在这篇文章中，我们回顾了我们最近关于捕获激子的实验，以及它们与激子BEC的相关性
While it has long been known that the ground state of spatially indirect excitons is optically inactive [1], its relevance to Bose-Einstein condensation (BEC) has been overlooked. In the past, signatures of excitonic BEC have been sought in the form of directional luminescence or coherence of the light emitted by excitons. In this contribution, we review our recent experiments on trapped excitons, and their relevance on excitonic BEC
